*biotech · news · 2026-06-08 · NDTV.com*

## Key points

- Zenagamtide 將 GLP-1 與胰淀粉素受體激動劑結合於單一分子，實現雙重代謝作用。
- 第二期臨床試驗中，服用 40 毫克 Zenagamtide 的參與者在 36 週內體重減輕高達 14.6%。
- Zenagamtide 的體重減輕在 36 週後尚未達到平台期，顯示可能持續減重。
- 患者僅在前 4 週接受完整 40 毫克劑量，卻見到高度有效的結果。
- 諾和諾德已根據這些第二期結果啟動更大規模的第三期 AMAZE 計畫。

Novo Nordisk's investigational drug zenagamtide has shown an average weight loss of up to 14.6% in individuals with type-2 diabetes. According to the data from the positive phase 2 trial presented at the 2026 Scientific Sessions of the American Diabetes Association (ADA) in New Orleans, LA, zenagamtide is the first drug of its kind to combine two separate biological keys that control metabolism into one single molecule: a GLP-1 receptor agonist and an amylin receptor agonist. While the study primarily focused on the drug's impact on blood sugar levels, the findings revealed that trial participants taking zenagamtide, once weekly, saw a mean body weight reduction of up to 14.6% with the 40 mg dose compared with 2.1% with placebo, a dummy treatment with no medicine. Impact on blood sugar levels Over the 36-week trial, zenagamtide dramatically reduced HbA1C levels. The 36-week study tested different doses of the drug against a placebo. Participants started with a baseline HbA1C of 7.8%. Patients taking zenagamtide saw a significant drop in their HbA1C levels. Higher doses, 40 mg, lowered HbA1C by up to 1.71 % compared to just a 0.14 drop in the placebo group. Up to 91.4% of patients across the trial doses hit target glycemic efficacy metrics. Weight loss effect Even though the main focus was blood sugar, patients taking the drug lost a substantial amount of weight. From a starting average body weight of roughly 99 kgs (219 lbs), those taking the highest 40 mg dose saw an average body weight reduction of up to 14.6%. In comparison, patients taking the placebo only lost about 2.1% of their weight. Weight loss without plateau The scientists noted that the weight loss had not plateaued by week 36, meaning patients would likely continue to lose more weight if they stayed on the higher doses longer. Furthermore, because of the way the trial was designed, the patients on the highest doses were only taking that final maximum dose for a very short period, which was just 4 weeks for the 40 mg dose. Despite this short exposure, the results were highly effective. About zenagamtide Zenagamtide, formerly known as Amycretin, is an experimental, dual-action metabolic medication under development by Novo Nordisk. Unlike older weight loss medications like semaglutide (Wegovy/Ozempic), which target only one hormone receptor, GLP-1, zenagamtide is a unimolecular peptide agonist that targets two distinct metabolic pathways simultaneously: GLP-1 Receptor Agonist: Mimics the GLP-1 hormone to stimulate insulin secretion, lower blood sugar, and target brain regions to reduce hunger. Amylin Receptor Agonist: Mimics amylin, a hormone co-secreted with insulin that suppresses appetite, slows down food transit, and enhances feelings of fullness. By combining these two mechanisms into a single molecule, it maximises appetite suppression and glucose regulation. Martin Holst Lange, chief scientific officer and executive vice president, Research and Development at Novo Nordisk, explained that these results prove the drug has strong potential to meaningfully improve blood glucose control for type 2 diabetes patients while simultaneously helping people manage obesity. "These results underscore our scientific leadership and position us to continue advancing innovative treatment options that could expand the therapeutic landscape and provide patients and healthcare professionals with greater choice in managing type 2 diabetes and obesity," said Martin Holst Lange. After these positive results, Novo Nordisk has already moved forward with a larger Phase 3 study, called the AMAZE program, to further evaluate the drug.
